Multiple VXLAN tunnel reachability

A method of creating a single egress object to a virtual link trunking (VLT) peer to allow multiple VXLAN tunnels to be reachable through an inter-chassis link (ICL) with optimal paths towards all next hops, comprising:

• sending, from a host, native unicast/broadcast traffic towards a first VLT peer VLT peer1;
• picking, in the first VLT peer, a single next hop router of a plurality of next hop routers reachable through the same ICL port channel of the host;
• and
• in the event of an uplink failure, modifying a routing protocol of the single next hop router to contain the ICL port and the MAC address of a valid VLT peer coupled to one of the next hop routers;
• and
• resolving VXLAN tunnels through an ICL link aggregation (LAG) process using the default egress object created on the ICL to route all traffic from the VLT peer1 intended to go through ICL to be terminated on a VLT peer2 and be sent to any respective next hops.

A system comprising a processor-based executable module configured prevent traffic from tromboning in a VXLAN network having routers that do not support multiple next hops via the same outgoing port, comprising:

• a first component creating, during an initialization step, a default egress object through an inter-chassis link (ICL) with a next hop defined as virtual link trunking (VLT) peer2;
• a second component setting a MAC address to be the MAC address of the VLT peer2;
• a third component setting a virtual LAN (VLAN) address to be one of a plurality of layer 3 (L3) spanned VLANs;
• and
• a resolver resolving VXLAN tunnels through an ICL link aggregation (LAG) process using the default egress object created on the ICL to route all traffic from a VLT peer1 intended to go through ICL to be terminated on the VLT peer2 and be sent to any respective next hops.
